'ALBERT MAUREB., 'or NEW remitir. 'A 1 TABLE FOR BALDI() APPARATUS.

Application med January 28, 1924. Serial No. 688,905.

To all whom. it may concern.'

Be it known that I, ALBERT MAURER, a citizen of the United States, and aresident of New York city, in the county of New York and State of NewYork, have invented certain new and useful Improvements in Tables forRadio Apparatus, of which the following is a specification.

The invention relates to an article of furniture such as a table orcabinet for mounting readily therein an antenna of the loop type as usedin radio reception; and it has for its object to so mount the sametherein that it will not project beyond the structure during operationand that it may conveniently be rotated to various positions in selectina station, as by a manually operable mem er extending beyond the outeredge of the top of the table portionv of the cabinet. The invention hasfor a further object to provide a loop support which will admit ofexpeditiously securing the said loop to the top of the table in mannerto, be

rotatable relatively thereto. A further object of the invention consistsin so constructing the improved article that a smooth table top may bepresented for receiving and loud speaker apparatus, and that the loop aswell as any other apparatus supported in the structure may be entirelyconcealed, if desired.

The nature ofthe invention, however, will best be understood whendescribed inconfnection with the accompanying drawings,l in" Fig. 1 is afront view of the improved cabinet with loop in position, and thecontrol shaft therefor shown in section.

Fig. 2 is a vertical section taken on the line 2 2, Fig. 1. l

Fig. 3 is an enlarged detail section illus-v tlatfiig the manner ofmounting the loop s a Similar characters of reference designatecorresponding parts thruout the several views.. v l Referring to thedrawings, 10 designates l a table top of suitable dimensions and whichis supported upon. uprights, preferably in former is provided withshelves 15 as "for supporting the (A) and (B) batteries and likeapparatus utilized in connection with aslaforesaid,

radio receiving and loud speaking apparatus 16 which may be supportedupon the upper surface of the table 10, it being desirable usually toconceal the former. In the compartment 14, the arrangement is such thata loopv antenna 17 may be completely rotated therein, and the samedepends for this purpose from the table top 10. To this end, a sleeve 20is provided thru the table top and extends slightly below the lowersurface thereof as shown. Thru'this sleeve is designed to pass forrotation therein a screw, the shank 21 of which fits thru said sleeveand Whose head 22 is counter-sunk in the upper end of the sleeve and issubstantially Hush with the upper surface of the table. The threaded end23 of the screw is 'screwed into the shaft end 24 or axle of the loopand effects" thereby a rigid connection be,- tween the two. Thisarrangement affords a very convenient means for securing the loop to.the table, as the same may be expeditiously performed from the uppersurface Vvof the table by the use of an ordinary screw driver.

' The shank`21 carries, also, a wormwheel vv25, which vit will beunderstood is to be secured to the shank prior to the attachment of theloop thereto and said worm wheel is designed' to mesh with a worm 26 ona worm shaft 27 extending beneath the table Suitablehangersf28*securedto the under face of the table afford bearings for-this shaft; and thesame .carries at its'fouter' endv means for eecting rotation of same,for example,

moreover, that this vis effected conveniently by turning'the lmob 30thereof in the usual manner, which rotates thereby the worm shaft andworm 26 andthru the engagement of the latter with the worm wheel 25effects -a corresponding rotation of the loop.
